AlternateReplicationServicePointAccessuint16
DescriptionstringRemote replication provides StorageConfigurationService instances for source systems and target systems.

If the primary instance is unavailable, the provider may indicate an alternate instance. Values: None: no alternate exists. Source: invoke to source element service instance. Target: invoke to target element service instance. Proxy: find and invoke alternate proxy service instance.
